Download module/Theme tar.gz file using command line

Good idea! I'll take a look at your patch soon. Thanks!

Here is a patch file showing the proposed changes to the extend-manual-install.txt file.

I think the basic idea is maybe OK, but the wording and formatting would need some adjustment:
- Not everyone has a mouse, or a mouse with two buttons. So the instructions to right-click to copy the link address would need to be modified somehow.
- There are some lines longer than 80 characters.
- The wording seems a bit awkward.
- There are some trailing spaces at the ends of some lines.
- The initial . in all the lines will format as additional numbered steps, whereas this is really just an addition to one step.

So, I am marking this Needs Work and will propose an alternative.

Here's a new proposal.

This looks fine to me. @amarphule did you have any further feedback on this? I would be fine with it being committed as is.

Updating it's version number, as it was not solved on 8.x-6.0 branch.

Thanks again! Committed, and email to the translation email list is going out shortly.
